Subject: [PATCH 1/1] SUNRPC don't resend a task on an offlined transport

From: Olga Kornievskaia <[email protected]>

When a task is being retried, due to an NFS error, if the assigned
transport has been put offline and the task is relocatable pick a new
transport.

Fixes: 6f081693e7b2b ("sunrpc: remove an offlined xprt using sysfs")
